A case of malignant myoenithelioma in the hard palate

Abstract

A rare case of low grade malignant myoepithelioma arising from the hard palate is reported. The CT findings indicated a defect of the hard palate due to the tumor. Surgery combined with postoperative irradiation therapy was performed. A histopathological examination indicated that the tumor originated in the myoepithelial cells, invaded the hard palate, and also showed cellular atypia with rare mitoses. Malignant myoepithelioma clinically shows a low sensitivity to both radiation therapy and chemotherapy. Surgery should thus be the first choice of treatment.
